The California State Water Project (SWP) is a multi-purpose water storage and delivery system that extends more than 705 miles -- two-thirds the length of California. A collection of canals, pipelines, reservoirs, and hydroelectric power facilities delivers clean water to 27 million Californians, 750,000 acres of farmland, and businesses throughout our state.

Planned, built, operated and maintained by the Department of Water Resources (DWR), the SWP is the nation’s largest state-owned water and power generator and user-financed water system. The project is considered an engineering marvel that has helped fuel California’s population boom and economic prosperity since its initial construction.
